Simply put, I was cheated by this company, but I admit that it was partly because of my career plan.
First of all, see clearly whether the job introduced is a full member or a dispatch. Dispatch is just like domestic labor dispatch. Please be careful if you are not desperate. Moreover, it is not just like this in Japan. Don't think that sending people to Japan before jumping ship. Once you send someone, you will be marked with a sign of sending in Japanese society, and it will be very, very difficult to jump into a club again.
If you are a full member, your social status is relatively normal, but you are optimistic about salary and working hours. Some units work overtime more than 100 hours per month. If you want to simply exchange money for that body, you can try.
Finally, for students who have just graduated or are about to graduate, don't trust the rhetoric of any headhunters and such intermediary companies easily. Be sure to think clearly about what you really want before making a decision.
